Introduction
KYN28-12 removable AC metal-clad switchgear (short for panel as below) is a new product, designed and developed by Enrich, based on the introduction of advanced foreign design and manufacturing technology. It will be a substitute for old fashioned metal-enclosed switchgear, such as KYN-12, JYN-12, GFC-12, etc. The panel applies to 3.6~12kV 3 phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It can be arranged for single busbar, single busbar sectionalizing system or double busbar. It accords with IEC62271-200 AC Metal Enclosed Switch and Control Equipment above 1kV and below 52kV IEC60694 Standard Common Clauses for HV Switchgear, DIN. VDE AC Switchgear at Rated Voltage Above 1kV, GB3906 3~35kV AC Metal Enclosed Switchgear and so on. It has perfect and reliable prevention function against mis-operation.
Ambient conditions
1. Ambient temperature:-10ºC~40ºC,daily average≤35ºC.
2. Altitude:≤1000m.
3. Relative humidity: daily average≤95%, monthly average≤90%.
4. Earthquake intensity: ≤8 degree.
5. Applicable occasions should be free from inflammables, explosives, corrosives and severe vibration.
Structure
The enclosure is made of aluminium-zinc plated steel sheet by CNC machine, high precise dimension, short production cycle, excellent mechanical strength and nice appearance. The busbar compartment, VCB handcart compartment, cable compartment and relay compartment are separated by metal sheet. Flexible operation for handcart movement, clear position instruction, the earthing switch allow to making short circuit current and creditable mechanical interlock. It fit with many kinds of handcart circuit breaker such as VD4, VS1 and VEN1-12 etc, and also select FK(R)N32-12 fixed load breaker switch or VC series vacuum contactor. The panel adopts air insulated, the door of circuit breaker have the function of anti- explosion, tested by internal electric arcing fault, without any welding contacts on the panel, mechanical and electrical locking design, the product conforms to GB 3906, GB/T11022,IEC 62271-200,DL/T404 standards , and passed domestic and Netherlandish KEMA test.
